That sounds fine running em at that schedule, I don't have experience with MH or T12's at all, I'm only used hps, and saying that I'm only on grow number 2, I did research the shit out of it 18 months before sewing any seeds tho so I'd have some head for it
you'll do just fine with the t12 anyway, it's all about the HPmuthafuckinS lights man for top notch results and yes I totally understand hoe everybody contradicts eachother online, best thing to do is just figure out what works for you or if you have the time research the shit out of everything.
Good movr taking the wrap away from them too, as soon as they break the soil you can remove it, just keep humidity levels up and you'll breeze through the seedling stage, i usually spray feed em the same amount as you're doing, maybe a light 250-300ml of water every few days,you don't want the roots missing out of that sweet water action, you can start adding nutes at day 14ish when the plant has established a nice root structure
